state_test/smm_test selftests are failing on AMD with:
"Unexpected result from KVM_GET_MSRS, r: 51 (failed MSR was 0x345)"
MSR_IA32_PERF_CAPABILITIES is an emulated MSR indeed but only on Intel,
make svm_has_emulated_msr() skip it so it is not returned by
KVM_GET_MSR_INDEX_LIST.
Fixes: 27461da31089 ("KVM: x86/pmu: Support full width counting")
